Systems for Facilitating Augmented Reality-Assisted Medical Procedures

2. The system of claim 1, wherein the retaining structure comprises a spectacle frame.

3. The system of claim 1, wherein the retaining structure comprises a helmet.

4. The system of claim 1, further comprising two lenses, each of the two lenses being positioned between a respective one of the two optical combiners and a respective one of the eyes of the medical professional, wherein each of the two lenses redirects light from a respective optical combiner so that the projection of the selected images appears to be closer than infinity to the eyes of the medical professional.

5. The system of claim 4, wherein the selected images are adapted to be in focus at approximately 50 cm.

6. The system of claim 1, wherein the screen is formed of an array of liquid crystal pixels.

7. The system of claim 6, wherein the array is a rectangular array.

8. The system of claim 1, wherein the one or more processors are configured to render at least a section of the screen at least partially opaque.

9. The system of claim 8, wherein the section is a circular section.

10. The system of claim 1, wherein any misalignment between the projection of the selected images and the region of interest is less than 2 cm.

11. The system of claim 1, wherein the optical combiners are of a waveguide type.

13. The system of claim 12, wherein the retaining structure comprises a spectacle frame.

14. The system of claim 12, wherein the retaining structure comprises a helmet.

15. The system of claim 12, further comprising two lenses, each of the two lenses being positioned between a respective one of the two optical combiners and a respective one of the eyes of the medical professional, wherein each of the two lenses redirects light from a respective optical combiner so that the projection of the selected images appears to be closer than infinity to the eyes of the medical professional.

16. The system of claim 15, wherein the selected images are adapted to be in focus at approximately 50 cm.

17. The system of claim 12, wherein the screen is pixelated.

18. The system of claim 17, wherein the screen is formed of an array of liquid crystal pixels.

19. The system of claim 12, wherein each optical combiner comprises a waveguide configured to transmit light coming from a respective one of the two micro-projectors into the eyes of the medical professional so as to display the selected images from the database as an augmented reality display.
